Human noroviruses (NoVs) are the leading cause of food- and waterborne outbreaks of acute nonbacterial gastroenteritis worldwide. As a result of the lack of a mammalian cell culture model for these viruses, studies on persistence, inactivation, and transmission have been limited to cultivable viruses, including feline calicivirus (FCV). Recently, reports of(More)
We have genotyped 53 individuals from three ethnic groups (Japanese, Chinese, Asian Indian) for an allotypic polymorphism of a widely expressed low affinity Fc receptor for IgG (Fc gamma RIIA). The method, requiring PCR amplification of genomic DNA and Southern analysis with allele specific oligonucleotide probes, detects a single nucleotide difference (G(More)
Symbiotic ectomycorrhizal associations of fungi with forest trees play important and economically significant roles in the nutrition, growth and health of boreal forest trees, as well as in nutrient cycling. The ecology and physiology of ectomycorrhizal associations with Pinus sp are very well documented but very little is known about the molecular(More)
To evaluate the potential role of human placental endothelial cells in the transport of IgG from maternal to fetal circulation, we studied Fc gamma receptor (Fc gamma R) expression by immunohistology and immunoblotting. Several pan-Fc gamma RII Abs that label the placental endothelium displayed a distribution pattern that correlated well with transport(More)
The IgG transporter responsible for ferrying maternal IgG across the human placenta to fetal circulation has not been identified, although the human homologue of the neonatal rat Fc receptor (FcRn), a heterodimer with pH-dependent IgG affinity, structurally similar to MHC Class I molecules, was recently proposed as a candidate. Affirming this hypothesis, we(More)
Heparin induced thrombocytopenia (HIT) is characterized by the formation of antibodies that activate normal donor platelets in vitro in the presence of heparin. We asked whether the commonly observed donor-specific variation in the platelet aggregation response to HIT antibodies is influenced by the density of Fc gamma RII on platelets or by the Arg/His 131(More)
This research aimed to evaluate the effects of adding a combination of exogenous enzymes to starter diets varying in protein content and fed to broilers vaccinated at day of hatch with live oocysts and then challenged with mixed Eimeria spp. Five hundred four 1-d-old male Cobb-500 chickens were distributed in 72 cages. The design consisted of 12 treatments.(More)
'Dysmorphic lung' is introduced as a term to describe any complex congenital malformation which involves both abnormal vascular morphology and disordered growth of a whole lung. The major group within this definition is the scimitar syndrome, which we choose to mean a hypoplastic lung with anomalous venous drainage and various degrees of collateral arterial(More)
Pure cultures of ruminal bacteria characterized as using only a single forage polysaccharide (Fibrobacter succinogenes A3c, cellulolytic; Bacteroides ruminicola H2b, hemicellulolytic; Lachnospira multiparus D15d, pectinolytic) were inoculated separately and in all possible combinations into fermentation tubes containing orchard grass as the sole substrate.(More)
1. Diabetes had no significant effect on IGFBP-3 message and serum levels however, subsequent insulin treatment caused more than a two-fold increase in both hepatic IGFBP-3 mRNA and serum levels above controls (P < 0.05). 2. The induction of diabetes in pigs significantly increased the steady state levels of IGFBP-2 mRNA in the liver of young swine (P <(More)
